The efficacy of orally administered mycophenolic acid (MPA), an inhibitor of guanosine monophosphate (GMP) synthesis, for the treatment of psoriasis, was studied in a double-blind fashion. Of twenty-one patients completing the study period, ten of eleven patients treated with MPA had a greater than 25% decrease in severity score compared with only two of ten patients treated with placebo. The placebo group had a slight increase in severity score compared to almost 50% reduction in the average severity score of the MPA-treated group. After termination of the double-blind portion of the study, the placebo group was treated with MPA and showed a 60% decrease in severity score. Adverse effects encountered included anorexia, nausea, vomiting, and diarrhea. One patient had an uncomplicated episode of herpes zoster. Other than a mild decrease hemoglobin, no hematologic toxicity was noted.

24 days after starting treatment of psoriasis with fumaric acid derivatives (0.8-1.0 g orally, plus unknown quantities locally) a 21-year-old woman developed acute oliguric renal failure with a rise of serum creatinine levels to 1094 mumol/l (12.4 mg/dl). Deterioration of renal function had been preceded by severe abdominal symptoms with nausea, vomiting and colicky pain. On admission to hospital she was dehydrated with hyponatraemia and hypokalaemia. There was glomerular microhaematuria, increased excretion of renal epithelia, and tubular proteinuria. Renal biopsy demonstrated acute tubular damage with vacuolization of proximal epithelia, dilated tubules and scattered necroses. After intermittent haemodialysis (13 courses over two weeks) renal function gradually recovered, as demonstrated at a follow-up examination four months after discharge.

Over a period of 4 years, 20 patients suffering from severe forms of psoriasis (erythrodermic, sub-erythrodermic, resistant generalized forms and/or forms associated with acute arthropathy) were treated with 96 h of continuous i.v. infusion of somatostatin (Stilamin, Serono) diluted in D5W at 250 micrograms/h. In addition to the usual blood chemistry parameters, circadian levels of growth hormone (GH) and epidermal growth factor (EGF) were measured before, during, and after therapy. Approximately 2-3 weeks after termination of therapy, erythrodermic and suberythrodermic symptoms had disappeared. In some patients, a few lesions of psoriasis vulgaris remained, although they were much less severe. Remission of acute arthropathy was impressive. Blood chemistry parameters were unchanged after therapy. Circadian levels of GH and EGF, normal before therapy, were significantly decreased after therapy. The infusion was well-tolerated. Infusion rates of greater than 250 micrograms/h caused only some complaints of abdominal pain, nausea, and vomiting. During the 4 years, erythrodermic symptoms reappeared only in seven patients, three of whom were also arthropathic. After 6-8 months, they underwent a second course of somatostatin therapy with good results. The other patients are still able to control their disease with tar-based products alone or with low-dose 8-methoxypsoralen + UVA (PUVA) or UV therapy. The arthropathic patients control their symptoms with periodic low-dose nonsteroidal antiinflammatory drug therapy.

A clinical phase I-II evaluation of 2-amino-1,3,4-thiadiazole (A-TDA) administered daily, twice a week, or weekly was undertaken, in which 71 patients were treated with a range of doses from 2 mg/m2 to 200 mg/m2. Pharmacokinetic studies employing high-performance liquid chromatography (HPLC) demonstrated a terminal (beta) serum half-life of 2.19 h. Stomatitis, dermatitis, nausea, vomiting, and lethargy were observed. No significant leukopenia or thrombocytopenia, however, was noted. A-TDA administration led to hyperuricemia, which was adequately controlled with concurrent administration of allopurinol. Antitumor responses included one partial response in a patient with large cell carcinoma of the lung and three objective responses (2 non-small cell lung and 1 squamous cell carcinoma of the esophagus). Two patients with adenocarcinoma of the lung had a marked improvement of psoriasis during A-TDA therapy. Further phase II studies in patients with cancer and trials in patients with psoriasis are recommended.

Sixty patients suffering from psoriasis of all clinical forms have been treated with an increased dosage of Bromocriptin. The age of the patients ranged from 20 to 72 years. Patients with contraindications for Bromocriptin were excluded from the test. In 80% a remission or reduction of psoriasis lesions was noticed. Side effects in the form of nausea, dizziness and vomiting occurred in 15%, but decreased in the course of Bromocriptin therapy.

Methotrexate, a folic acid antagonist, is approved by the US Food and Drug Administration for use in rheumatoid arthritis, psoriasis, and various types of cancer, including choriocarcinoma, and has also been used to terminate ectopic pregnancies. Misoprostol, a prostaglandin, is approved for the prevention of gastric ulcers induced by nonsteroidal anti-inflammatory drugs. In France, the UK, and Sweden, misoprostol and another prostaglandin is used with mifepristone (RU486) to induce abortion in early pregnancy. Recent articles in the press have suggested that in early pregnancy, an intramuscular injection of methotrexate and oral or vaginal administration of misoprostol offers a medical alternative to a surgically induced abortion. This paper describes the mechanisms of action, pharmacokinetics, clinical use, and adverse effects of the two drugs. It is concluded that an intramuscular injection of methotrexate followed up to seven days later by the intravaginal administration of misoprostol can terminate an early intrauterine pregnancy. Headache, nausea, vomiting, diarrhea, and prolonged bleeding have occurred. However, in the few studies published to date, no serious complications have been reported.

The field of neuropeptides has been expanding very rapidly in recent years. Apart from understanding their physiology and elucidating their functional role as putative neurotransmitters, research has focused on producing drugs that may treat a variety of illnesses in a novel way. Substance P antagonists occupy a central role in this area of intensive scientific activity. Substance P (SP), an undecapeptide, is abundant both in the periphery and in the CNS, where it is usually co-localised with one of the classical neurotransmitters, most commonly serotonin (5-HT). A role for SP is proposed in the regulation of pain, asthma, psoriasis, inflammatory bowel disease and, in the CNS, emesis, migraine, schizophrenia, depression and anxiety. A recently published positive study of MK 869, in depression, a novel SP antagonist has generated excitement amongst psychopharmacologists. It is the first time that a drug, not directly related to monoamine transmitters, has showed efficacy in depression. Although MK 869 has been suspended from further development, a host of other compounds, with similar action and better pharmacological profile, are currently under development. In this review, the pharmacology of central SP and its receptors are discussed, together with the exploration of the prospects and implications for future treatments of depression.

Substance P (SP) is a neuropeptide which is abundant in the periphery and the central nervous system, where it is colocalized with other neurotransmitters such as serotonin or dopamine. SP has been proposed to play a role in the regulation of pain including migraine and fibromyalgia, asthma, inflammatory bowel disease, emesis, psoriasis as well as in central nervous system disorders. This review summarizes our current knowledge of the role of SP in the pathogenesis of neuropsychiatric disorders with special emphasis on affective disorders including bipolar disorders. It also reviews current treatment approaches with neurokinin 1 receptor antagonists which appear to be promising drugs for the future treatment of affective disorders.

We present an interesting case of salicylism arising from the use of methyl salicylate as part of a herbal skin cream for the treatment of psoriasis. A 40-year-old man became quite suddenly and acutely unwell after receiving treatment from an unregistered naturopath. Methyl salicylate (Oil of Wintergreen) is widely available in many over the counter topical analgesic preparations and Chinese medicated oils. Transcutaneous absorption of the methyl salicylate was enhanced in this case due to the abnormal areas of skin and use of an occlusive dressing. The presence of tinnitus, vomiting, tachypnoea and typical acid/base disturbance allowed a diagnosis of salicylate toxicity to be made. Our patient had decontaminated his skin prior to presentation, limiting the extent of toxicity and was successfully treated with rehydration and establishment of good urine flow.

There is considerable evidence to support an immunopathogenic basis of psoriasis. However, changes such as altered angiogenesis have also been implicated in the pathogenesis of psoriasis. AE-941 (Neovastat; Aeterna Laboratories, Quebec City Quebec, Canada) is a naturally occurring product currently in clinical investigation that blocks two main mechanisms of angiogenesis activation, namely, vascular endothelial growth factor and matrix metalloproteinase. We hypothesized that psoriasis could be modulated by inhibiting the neovascularization of psoriatic plaques. We conducted a randomized dose-comparison trial to evaluate the safety and potential therapeutic benefit of AE-941, administered orally to patients with psoriasis. Forty-nine patients with psoriasis were enrolled and assigned to receive AE-941 at 30, 60, 120, or 240 mL/d for 12 weeks. Patients were followed up for another 12-week period. Improvement in the Psoriasis Area and Severity Index (PASI) score was observed in 50%, 41.7%, and 30.8% of the patients receiving 240, 120, and 60 mL/d, respectively. No patients receiving a dosage 30 mL/d showed a PASI score improvement. A statistically significant improvement with increasing dose was observed for the PASI score, severity of itch, and the physician's global assessment. The most commonly reported nonserious drug-related adverse events affected the gastrointestinal system in 12 of 49 patients (primarily nausea, diarrhea, vomiting, flatulence, and constipation) and the skin and appendages in 4 of 49 patients (primarily acne and rash). This randomized phase I/II study provides evidence that the antiangiogenic agent AE-941 offers a new therapeutic approach to the management of psoriasis.
